我正在尝试将十进制数转换为二进制数。我想将模数存储在一个数组中,然后打印结果。结果必须向后打印。到目前为止,这是我的代码。当它运行时,会出现一条消息,说unaligned address,exception 5
。到目前为止,这是我的代码
.data
prompt1: .asciiz "\n\n Please give the decimal number:"
prompt2: .asciiz "The binary number is:"
array: .space 32
linefeed: .asciiz "\n"
enterkey: .asciiz "Press any key to end program."
.text
main:
li $t0,0
li $t3,2
li $s0, 0
li $a0, 0
#t1-to hold number
li $v0, 4 #syscall to print string
la $a0, prompt1 #address of string to print
syscall
li $v0, 5 #syscall to read an integer
syscall
move $t1, $v0 #move the number to read into $t1
for:
bge $s0, 8, end_for
div $t1,$t3
mflo $t1 #diversion
mfhi $t1 #modulus
sw $t1,array($t0) #save the number to read into array
addi $t0,$t0,4
addi $s0,$s0,1
j for
end_for:
# print out a line feed

move $a0,$t0
syscall

# wait for the enter key to be pressed to end program

syscall # print enterkey
# wait for input by getting an integer from the user (integer is ignored)
li $v0,5 # code for read_int
syscall #get int from user --> returned in $v0
# All done, thank you!

syscall # exit program
